Pre-Event Workshop – ABC Waters

An Insight To Singapore’s ABC Waters Management Strategy


The Active, Beautiful, Clean Waters (ABC Waters) Programme is a long term strategic initiative by PUB, Singapore’s national water agency, that aims to transform utilitarian canals, drains and reservoirs in Singapore into clean flowing rivers, streams and lakes that blend naturally into the urban environment. The objectives of the programme is two-fold: (1) to create inviting and vibrant spaces around our waterways and waterbodies to bring people closer to water so that they appreciate and cherish our valuable water resource, and (2) to adopt a sustainable stormwater management strategy to detain and treat stormwater runoff close to source before discharging to downstream waterways and reservoirs. This sustainable approach in managing runoff is also termed as Water Sensitive Urban Design (WSUD) in Australia, Low Impact Development (LID) in USA, or Sustainable Urban Drainage Systems (SUDS) in much of Europe.

Under the ABC Waters Programme, PUB has embarked on a journey to harness the full potential of our waters by integrating them with our environment. Over the years, other public agencies and private developers have also embraced ABC Waters design, leading to improvement in water quality, enhanced biodiversity and new recreational spaces for people to get closer to water. The use of ABC Waters design features (environmentally sustainable green features made up of soil and plants) such as rain gardens, bioretention swales, vegetated swales and constructed wetlands will help to minimise the hydrological impacts of urbanised catchments and also safeguard water quality in our reservoirs and waterways.

Workshop Objective

  • To provide participants an insight to the Active, Beautiful, Clean Waters concept to manage our stormwater sustainably, while at the same time enhancing our urban environment.
  • To give an overview of the principles and applications of ABC Waters design features.
